Iam doing some unit testing using netbeans IDE and JUnit. Can JUnit be used to check the values of local variables in various parts of a method.eg. can the values of var1 and var2 determined using JUnit:
JUnit can also be used to test for certain side effects of method calls, but that's rather deep in the bag of tricks.
It cannot be used to test the values of local variables. If you feel the need to do that, it is almost invariably an indicator that your design could use some improvement.
Unfortunately, your example code is too general to give more specific advice. If you post some real code, I'm sure we can be more helpful.

So one thing that Ilja means by "improving the design" is that you can take any condition or logic that leads to setting the value of a local variable, and break it out into a separate small method. Then you can test that small method by checking its return value! In this way, test-driven design leads you toward designs with many small, testable methods. If the small methods have good names, then this kind of code is very easy to read, too -- a plus!

Mhh, yes, that's one possible solution - there are of course uncounted others. What a good solution looks like very much depends on what the code really looks like.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
